EDWARD W. TYRRELL, OF PROVIDENCE, RHODE ISLAND.

HORSESHOE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 230,450, dated July 27,1880.

Application filed December 13, 1879.

To all whom it may concern:

Be it known that I, EDWARD W. TYRRELL, of Providence, in the county ofProvidence, and State of Rhode Island, have invented certain new anduseful Improvements in Horseshoe-Machines; and I do hereby declare thatthe followingis a full, clear and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to improvements in that class of devices known asmachines for the manufacture .of horseshoes, and it consists in thenovel construction and arrangement of the various parts, whereby a barof iron is fed to the machine after leaving the rolling-mill. Said baris first creased and then cut the desired length, and at the same timepressed to the desired form, for the shape of the heels of the shoe.

The bar is then bent around a suitable former, after which it is passedbeneath a hammer and pounded a suflicient number of blows, after whichthe shoe-blank passes from the machine, all of which will be hereinaftermore fully explained.

I construct a horseshoe-machine that allows of two shoes being made ateach reciprocation of the pitman, which may be a front and hind shoe, ortwo front shoes, or two hind shoes.

The two operating parts being alike, I will describe but one portion ofthe machine.

The annexed drawings, to which reference is made, fully illustrate myinvention.

Figure 1 represents a front view of my improved horseshoe-machine. Fig.2 represents an end view of the same. Fig. 3 represents a verticallongitudinal sectional view. Fig. 4 represents a verticalcross-sectional view of the same. Fig. 5 represents a plan ortop viewwith a portion of the machine removed. Figs. 6, 7, 8, 9, 10, 11,12,13,14, 15, 16,17, 18, 19, 20, 21, 22, 23, 24, 25, and 26 representdifferent parts of the machine in detail.

Letter A designates a table supported by legs a a, and connected to oneanother at their lower ends by cross-pieces a a. In the top of the tableA is made a channel, A, of suitable width, running horizontally from endto end, a portion of whichin the center thereof is bottomless. On eitherside of the channel A aforesaid, and secured to the top of the table Aand arising therefrom, are vertical standards A A joined to one anothernear their lower ends by a block, ad, which also serves as a rest orsupport for the upper mechanism of the machine, which will be furtherexplained. The

tops of said standards are connected to each other by a curved bar, ahaving a perforation through its center to receive avertically-operating rod of the hammer a, above mentioned.

B designates a carrier placed within the channel A, the center portionof which is of skeleton form. The ends thereof are formed into asuitable block, b, on which is placed a die provided with the formers b,on which the shoes are made.

In the space between the bars that form the skeleton-frame and directlybehind each former is placed a lifting-plate, b adjustably secured tothe top of a vertically-moving block, b the sides of which are pointedand work within a corresponding groove on the inner face of the bars ofthe carrier aforesaid, as shown in Fig. 5 of the drawings. In the rearof said block b and between said bars is pivoted a trigger, b thehorizontal arm of which acts upon the under side of the block W. Intilting the same the downward arm b comes in contact and rides over ahorizontal bar, I), secured to the under side of the table.

In the center of the skeleton-frame above mentioned, running crosswiseof the same, is

a pin, the outer ends 0 of which project beyond said frame and enter aslot in the up- I per end of a rockinglever, O, which is secured at itslower end to a shaft, 0, running crosswise and beneath the table A. 9

D designates a carriage constructed of two bars, 61, traveling uponrollers 31 y, secured to the inside of the standards A A and connectedto one another by cross-bars d d, and

having on its under side a rack, d, in which meshes a small cog-wheel orpinion, d journaled to the table on either side of the chanand aroundthe bars d are springs d", and through each bar d of the carriage arescrews which press against each block 01 In the center of the slidingblock al is a perforation, through which is passed vertically a shortaxle, c", on the top of which is a loose roller, 0, and at the bottomthereof a loose flanged wheel, 0", that bends the shoe around the formerb. Directly above the carriage D, and secured to the inside of thestandards A and projecting inwardly, are bars a", through the end ofwhich passes an adjusting-screw that engages with the end of a guirlespring, 0", attached to said bar.

E designates a sliding frame, having its bearing in suitable bracketsfixed to the legs a, and provided with loose rollers e, upon which actsthe cam a secured to a shaft, 6 running crosswise of the machine, andsupported by standards or bearings e fixed to the cross-pieces a a Saidshaft 0 has on one end a cog-wheel, e, fixed thereto, which meshes witha smaller cog-wheel or pinion, 0 secured to a short shaft journaled insuitable bearin gs e upon cross-pieces a, and having a beltwheel, 0 anda fly-wheel, c.

On the shaft 6 and opposite to the cogwheel 0', is a flanged cam, 6 thatoperates a vertical lever, F, pivoted at its lower end to a projectionat one side of the standard or hearing 2 On the shaft 6 and to one sideof the cam e that operates the sliding frame aforesaid, is placed acollar, f, having projections f f, that act upon and operate a lever, G,the lower end of which is journaled in suitable bearings G G fixed tothe crosspiece of the frame. The portion of said lever G is providedwith a tooth, g, upon which acts the projection f above mentioned, andthe upper portion operates the cuttingknife, hereinafter mentioned.

H designates a plate bent at right angles at each end, secured to thetop of the table A at one side of the channel A. Said plate is bent atright angles upwardly, and is provided with perforations, through whichare passed stationary rods 7:, on the outer end of which is removablyapplied a block, h, having perforations similar to those of the plateaforesaid. Said block is recessed on its under side to receive acutting-bar, 7L2, both edges of which are beveled, and the centerportion, if, of which serves as a cutting-knife in separating the barsof iron out of which the shoes are made. Onposite said knife or beveledbar k is a cuttingbar, h, held in place by an adjustable bolt applied tothe plate it as shown in Fig. 5 of the drawings. 7

Through the top of the table A and in the front end thereof are slots I,in which are placed the lower ends of vertical standards 1', betweenwhich are secured a flanged wheel, i, and a creaser-wheel, i having oneside flanged and provided on its outer face with a cuttingedge orcreaser, i Said creaser-wheel, as Well as the flanged lower wheel,isjournaled in suitable boxes in the standards aforesaid, and prothatoperates the hammer a vided with adjusting-bolts i and below the boxwith a spring to aid in said adjustment.

Through the top of said standards, directly beneath the wheel, andsecured to the top of the table A, and running to the cutting-knivesaforesaid, is a trough or guide-box, i and opposite said trough'orguide-box, and secured to the front edge of the table A, is a looseguide-roller, t

On the inner end of the shaft that passes through the creaser-wheel iand the standards 1' is a disk having an adjustable arm, 6, on its outeredge, and provided with a loose roller, 2', that is operated upon by theupper end of the vertical lever F. Said lever passes up through a slot,f in the table A, and has fixed :thereto a spring, f, for a purposehereinafter mentioned.

A spring is secured to a block, f", on the top of the table A, that actswith thelever aforesaid. On the top of the block a a that connects thelower ends of the standards A A and between said standards, is placed aplate, a

having arising therefrom suitable bearings,

through which is passed a horizontal shaft, a, in or near the center ofwhich is a crank, a, Said crank a, passes through the journal-box a",which is composed of parts 2 2 z, sliding within the frame a of thevertical plunger a, on the bottom of which the hammer a is applied. Thelower portion of said box is so arranged as to allow sufficient space abetween that and the upper portion to prevent sudden jars to saidhammers.

A spring, .2, isinterposed between the surface ofthe part which enterssuitable holes 2 on the under side of the box a", for the purpose ofretaining the part 2 to the inner face of the frame, as shown in Figs.24, 25, and 26.

On the shaft a, to one side of the crank a is secured a worm-screw, a,and also a crankarm, at", having an adjustable pin, a" On the oppositeend of said shaft is secured one half, a, of a friction-clutch, A

Secured to the outside standard or hearing projects a rod, b upon whichworks a lever,

b", the upper portion of which is provided with a tooth, b, that engagesthe worm a and the lower longest arm, I)", of which connects with oneend of a forked lever, b the opposite end of which is pivoted to an arm,I), secured to a shaft, b, applied to a bearing on the outer face of thestandard A There is also applied to this end of the shaft a lever, f",the upper portion of which is provided With a Weight,f, and the lowerarm f of which engages with a short arm, f, of a curved arm, f ,thatispivoted to the outside of the block a".

On the short shaft g is secured a pulley, g and at each end thereof isadjustably applied the portion 9 of the friction-clutch A aforesaid.Said shaft has its bearings in the upper end of the standard g Securedto the inner end of the shaft b" is a cam, 9 that works in a slot madein the forward end of an angular'lever, g Said angular lever is pivotedto thestandard 9?, and atthe upper end, connects with a plate, 9', whichhas a lug, through which passes a screw, 9 that enters a V-shaped grooveon the outer face of the friction-clutch aforesaid.

Having thus described the different parts of which my horseshoe-machineis constructed, I

will now proceed to give the manner in whichit is operated.

Operation: The bar of iron out of which the shoes are made passes overthe roller i and enters between the creaser-wheel t and the lowerflanged wheel, 2'. At the same time the cog-wheel e is given motion bythe. pinion e on the shaft 0 on which the belt-wheel e" is applied. Thismovement conveys motion to the flanged cam e on the outer end of theshaft 6 Said cam strikes the roller 6 on the inner face of the verticallever F, and causes the upper end of said lever to strike the looseroller i on the disk aforesaid, and carries said roller therewith, atthesame time revolving the creaser-Wheel i and causing the creasers i tocrease the bar of ironand feed the same to the machine. The iron isguided by the trough or guide-box i into the space between the cut-.

tin g-bars k h The bar of iron is then pressed between the cutting-barsh h, in order to give the desired thickness to the heel of the shoe andat the same time taper said heels. The desired length is at the sametime out off, and the spring it throws the block it to its former place.of the carrier B, directly in front of the former. The carrier B andcarriage D move simultaneously in opposite directions to one another.This is caused by means of the slot 10, formed in the center of thesliding frame E, and operating upon a pin, Y, secured to one side of thelevers U, near the center thereof, and the slot in the upper end of thelever 0 operating upon the pins 0, secured to said carrier B, and, bythe cogs O on the upper end of the lever O, meshing with the small-cogor pinion G and the latter operating upon the under side of the carriageI). At the same time the flanged wheels 0 strike the bar of iron andcarry the latter around the former b about half-way. The rollers c thenstrike the incline plane of the guide-bars 0 thus causing the twoflanged wheels 0 on opposite sides of said former to move toward oneanother, thereby turning the heels of the shoe inwardly to its desiredshape. After the latter operation the block b, with the former b andshoe, remain directly beneath the hammer a. This is caused by the lostmotion in the time it takes the cam e to revolve and again come incontact with the opposite roller, 6, to that it previously left. Thehammer a is then brought into action by means of the clutch A revolvingwith the shaft a and pulley 9 At the same time the tooth b on the upperend of the lever b" engages with the screw and causes said lever a tomove outwardly upon the rod b until a sufficient number of strokes havebeen given by the hammer The bar then enters upon the block b a, afterwhich the pin a comes in contact with the upper end of said lever b andthrows the tooth b out of engagement with the wormscrew a thereby'causin g the forked lever b to act upon the shaft 1) and throw theweighted lever f outward. At the same time the spring on the rod bcauses the lever b to return to its former position, in order to bethrown into engagement again at the proper time, and by the movement ofthe shaft 1) the slotted angular arm g causes the clutch A to disengage,while the lower short arm, f, of the weighted lever f strikes the shortarm f of the curved arm f and throws said curved arm into its formerposition.

.The heel portion of the shoe is raised from the former b by means ofthe plate I) being struck on its under side by the short arm of thetrigger b, when the downward arm or trigger b engages with the raisedportion of the bar 11 beneath the table a.

In the backward movement of said trigger the same rides over said raisedportion of said bar b, and does not cause the plate 12 to rise after theshoe is raised, as before stated. The hook end of the curved arm fcatches the shoe and holds it, thus allowing the carrier B to move andleave the shoe upon a pan or receptacle, 00, attached to the endthereof. When the carrier Bis returning beneath the hammer a the hookedend of the curved arm is struck by the shoe on the former and thrownoutwardly, which causes the short arm f to strike the lower arm, f, ofthe weighted lever fflthereby causing the clutch A to act upon theshaft, which acts upon the hammer a and at the same time the tooth b isthrown into engagement with the worm-screw a by means of the forkedlever b" It will thus be seen by the foregoing description that when thecreasers make their partial revolution in creasing the bar of iron thespring f applied to the vertical lever F, causes the creaser-wheel i tomake a complete revolution by means of the spring f and the differentparts are constructed in order that the same may be adjusted to suit thedifferent thicknesses of iron and, further, the creasingwheels may beremoved and others for a different kind of a shoe substituted therefor.

The standards t' t can be moved toward or vfrom the main portion of themachine to allow IIO F G, operating alternately upon the opposite sideof the machine-that is to say, while one portion of the machine isengaged the other is disengaged.

It will also be seen that the movement of the hammers is caused to actonly when the die-block with its former and shoe is directly beneath thesame.

5 The formers may be removed and others substituted for different formsof shoes.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

10 1. The combination, with the carrier B,

former b, of the lifting-plates [2 applied to the block W, trigger I),and the horizontal bar .12, substantially as and for the purposes setforth.
